A number of other issues have already been addressed, but not the poor design of the regex. It's hard to imagine a regex much more fragile than your
      /(address............)/ #13 dots for 13 characters.

Will you never need to deal with address 6435 main ave or address 643 main st?

Update re reply: ... then the regex (still fragile, IMO because I don't believe in perfect data) might be more readably written as
      /=~ /(address.{13})/
